Abstract

This study develops a Website-Based Outsourcing Services Negotiation System for PT XYZ, addressing the company’s reliance on manual communication and document exchange, which previously caused delays and data inconsistencies. The system streamlines client registration, service submission, negotiation, and invoice generation. Extreme Programming (XP) was selected for its iterative adaptability to evolving user requirements, focusing on rapid prototyping, continuous feedback, and incremental improvement. An object-oriented design approach ensures modularity and maintainability, while black box testing validates functional accuracy. After deployment, negotiation process time was reduced by 35%, communication response time by 42%, and documentation completeness reached 100%, significantly enhancing operational efficiency, transparency, and record reliability. These measurable improvements demonstrate the system’s role in accelerating PT XYZ’s digital transformation and establishing a more structured, evidence-driven outsourcing negotiation process.
